We have a very high ceiling foyer in our building and occasionally a young toddler
will discover that when he or she laughs it echoes. Which prompts them to laugh
even more—with joyous abandon—looks like they like to hear the sound of their own laughter. Which brings a laugh or smile to our day.

So, if you can’t find a reason to laugh on any particular day, see if you can spot a
child out in your world—laughing with uninhibited delight. That might suffice
until you laugh again yourself.
